Entries linking to kinesthetics
kinesthetic adj.
also kinaesthetic, "pertaining to kinesthesia," 1880, coined by British neurologist Henry Charlton Bastian (1837-1915) from Greek kinein "to move" (from PIE root *keie- "to set in motion") + aisthēsis "sensation" (from PIE root *au- "to perceive"). The coinage is perhaps on model of aesthetic, prosthetic.
-ics
in the names of sciences or disciplines (acoustics, aerobics, economics, etc.), a 16c. revival of the classical custom of using the neuter plural of adjectives with Greek -ikos "pertaining to" (see -ic) to mean "matters relevant to" and also as the titles of treatises about them. Subject matters that acquired their English names before c. 1500, however, tend to be singular in form (arithmetic, logic, magic, music, rhetoric). The grammatical number of words in -ics (mathematics is/mathematics are) is a confused question.
